The Connect Series Half-Rack delivers one of the most feature-rich amplifier experiences available in the industry – in a smaller form factor. Featuring 96kHz DSP, WebUI, SharkWare, LEA Cloud, third-party APIs, speaker tunings, and more, this amplifier is the right choice for your next install. Each of the half-rack models (CS34, CS64, CS124, CS34D, CS64D, and CS124D) are built with fully routable analog inputs, four amplifier channels with Lo-Z, 70V, or 100V selectable by channel and D-units include Dante and AES67 connectivity. All models boast three different ways of network connection: using the built-in Wi-Fi Access Point, connecting to an existing Wi-Fi network, or using a Local Area Network Ethernet connection.
LEA Professional’s smart amplifiers are one of the most feature-rich amplifiers available in the industry – featuring onboard 96kHz DSP, cloud connectivity, WebUI, third-party API control, real-time load monitoring, Lo-Z/70V/100V selectable by channel, smart power bridge, fault monitoring, high-efficiency power design, over 3,000 speaker tuning presets, and LEA’s advanced amplifier control software, SharkWare.
By providing both mic and line-level inputs, the Connect Series half-rack becomes versatile and adaptable – capable of handling different audio sources with optimal strength and fidelity.
LEA’s IT capabilities offer versatile connectivity modes (Access Point, Wi-Fi, or Wired) catering to the most diverse installation needs. The widely integrated software platforms provide ease of use and flexibility – WebUI works across all browsers and devices, perfect for quick setups and simplified operation in smaller installations – while SharkWare empowers users with enhanced control options for more extensive audio setups and larger systems. Free cloud monitoring and control is also possible thanks to the LEA Professional Cloud, enabling remote support from anywhere, and minimizing system downtime. In addition, seamless integration with 3rd party APIs ensures adaptability within various system control solutions.
LEA leads in DSP advancements with 96kHz native DSP for superior sound accuracy. The Connect Series Dante models set new standards in AOIP performance, enabling seamless high-resolution audio networking. The all-in-one functionality (Input Matrix, Signal Generator, Crossover, PEQ, and Limiting Load Monitoring) eliminates the need for external hardware. Additionally, over 3,000 speaker tuning presets facilitate quick setup for any system size.
Connect Series amplifiers feature a high-efficiency smart power design in a compact form. Direct Lo-Z or 70V/100V selection per channel removes the need for separate amplifiers. The universal Switch Mode Power Supply ensures seamless operation across a wide voltage range. Most notably, Our Smart Power Bridge technology doubles power output on a single channel without compromising others.
Ideal for small to medium-sized installations, the Connect Series Half-Rack is a versatile 4-channel amplifier available in 30, 60, and 120 watts per channel models (CS34, CS64, CS124, CS34D, CS64D, and CS124D).
